New forms of refractive surgery result in corneas that are nearly doubled in thickness. To test the reliability of standard instrumentation for the measurement of intraocular pressure in such eyes, the MacKay-Marg tonometer was used on eye bank eyes with and without epikeratophakia lenticules and/or bandage contact lenses. The Goldmann applanation prism in the hand-held Perkins portable tonometer and the MacKay-Marg tonometer were used to measure IOP in vivo in a primate eye with an epikeratophakia graft. Measurements were compared with actual intraocular readings from a transducer. The MacKay-Marg tonometer was reliable at pressures above 20 mm Hg; the extra thickness of the graft and/or the rigidity of the contact lens impaired the accuracy below 20 mm Hg. The Goldman tonometer was accurate over the entire range of pressures.
新型屈光手术会使角膜厚度几乎翻倍。为测试在这类眼睛中测量眼压的标准仪器的可靠性，在有和没有角膜表层镜片术晶状体和/或绷带式隐形眼镜的眼库眼球上使用了麦凯 - 玛格眼压计。手持珀金便携式眼压计中的戈德曼压平棱镜和麦凯 - 玛格眼压计用于测量有角膜表层镜片术移植物的灵长类动物眼睛的活体眼压。测量结果与来自传感器的实际眼内读数进行比较。麦凯 - 玛格眼压计在压力高于20毫米汞柱时可靠；移植物的额外厚度和/或隐形眼镜的硬度在压力低于20毫米汞柱时会损害准确性。戈德曼眼压计在整个压力范围内都很准确。
